Facial Recognition Unnamed Faces & Hidden People - can we search the Hidden People Names to match with Unnamed

Is there a way to add the "names" of those who have been hidden when trying to name the "unnamed" - or is it best to just not "hide" anyone you want to name until you have gone through all of your "unnamed" 

Further information - I have just purchased Facial Recognition and I am labeling certain people then Hiding them (one example divorce of friends husband so still want to name him but don't care if I see him) - but then find that there are other "unnamed faces" that match him - I cannot "name" him because I have "hidden him", so then I have to go through and find where he is in Hidden, unhide him, then find the "unnamed face" of him again, then add his name
